Summary

In the present investigation the influence of various soil physical parameters on seeding emergence of corn (Zea mays L.) and their critical limits was studied in order to obtain a proper crop stand. The effect of soil compaction, resulting into various bulk densities on some soil physical properties was also studied. Seedling emergence decreased with increasing bulk density, soil suction, seed placement depth, soil strength and with decreasing oxygen diffusion rates. The critical values for these soil physical parameters were found to be 1.4 g/cm3, 3 atm., 4 cm, 1.0 kg/cm2 and 40×10-8 g O2/cm2/min bulk density, soil suction, seed placement depth, soil strength and oxygen diffusion rates respectively. Increasing bulk density decreased the soil water content, oxygen diffusion rates and increased the soil strength. re]19751117
